Working On Map - Criticism needed

So I have been on creative working on a map. I have plans for what map type it would be. And also have plans on what I will put on it. But I just built this and I wanna share it with you. See what you think. Maybe I could improve it using ur suggestions.

Plans:

ScreenShots:

Haven't done the interior and if you couldn't have guessed it, the theme is Hoth - Star Wars

Well I have had a change of plans since when I built the AT-AT so perfectly but then restarted and lost it. So instead of it being set in the time where the Emperor rules the galaxy, it is gonna be set during the Clone Wars!

"How will this happen, the only hoth battle in the movies is in Ep V one!!!!"

Well thanks for asking that! Fear not, in an episode of Star Wars the Clone Wars there is a Battle in Hoth!
